I figured you were going to use AOE world as your cited source and knew you weren’t using correctly when the term “high elos” was used. AOE World doesn’t have reliable data on high elos. This is due to low sample sizes in the higher range and because of how matchmaking is matching high and low elo players together. The developers of AOE World actually have a posted warning about using their stats like this on the AOE World’s FAQ.
Same developer replys to this post, saying essentially the same thing.
“I will just add that I never really wanted to add >1600 as a filter because I kept repeating in comments on Reddit that sample rate is just too low and always be too low which results in statistically insignificant win rates and a lot of fluctuation. Eventuality I caved in after many requests.”
Can Win Rate stats now be trusted? - An understanding of the data : aoe4 (reddit.com)
((you’ll also notice in that reddit post that win-rate data cannot be trusted until meta’s settle. Which we’re not even close to. You still see 1000 - 1300 Elo plant their Mongo TC in ridiculous spots, and that’s literally the first choice they make every game))
So, when you use AOE world, you need to do more than look at the green and red numbers on the main page to understand the data. Go into the actual match history and look at what’s skewing the numbers. What you’ll notice is a huge portion of the win numbers are mostly coming from tower rushes. 10-15 minutes wins. Which is exactly what the Devs are trying to fix.
Now Tower rushing isn’t a Mongol only issue. For example, Chinese are capable tower rushers as well. But Mongols are the Civ best suited for it, simply for being able to put most everything under TC for DA/FA and Yam. The underlying issue isn’t Mongols. It’s Tower Rushing. That’s what needs fixed. Nerfing Yam will not stop tower rushing, in fact it’ll probably make it worse on the general ladder (~1000 Elo) because Silver Tree is even more of a Meme.
Why does Tower Rushing need a universal fix? It’s way harder to defend than to execute (unless you’re Mongols). Which further muddys the data, because now Mongols arn’t being Tower Rushed, the most popular strat on the ladder, because they can simply move their buildings at will.
Again, issue is Tower Rushing. Not standardizing area of effects or whatever other sillyness people are claiming. It’s not a civ specific issue, it’s a general game issue, however there are civs better designed to execute it and defend against it. It would have been far better to completely remove outposts in the DA across the board. But instead heavily nerf’d Mongol Economy and Military in an attempt to curb a cheesy strat available to all civilizations.
